Talked to a neighbor who was a major in the Army. He said that as of now, he thought that there were some 20 US military bases left in Germany. Said he could find out for sure, but...
Anyway, asked me why I wanted to know and I told him. He agreed with our thoughts since the cold war is over, and being that Belarus and Ukraine are not part of the old Soviet government, that we should move closer to the front lines, so to say.
He said, in his opinion, that Germany has never been our friend, even after we re-built them after WW2. Unlike Japan, who has become one of our closest allies in the Pacific.
There are at least 20 US military bases in Germany. Seems like they’re just forward bases to the Middle East these days.
Good for you talking with your neighbor. 20 is a good number though there might be a few more; however during the Cold War we had over 200 posts in Germany. The 3d Armored Division alone was divided among a dozen kasernes (barracks) in a half dozen towns. Everyone of those is now closed and a few have been totally demolished.
Here is a Wiki article on US bases in Germany in the 1980s and now. It is fairly accurate as best I can tell: https://en.wikipedia.org/wiki/List_of_United_States_Army_installations_in_Germany
The strength of US Army Europe in the 1970s and 80’s when I was there was about 250,000 soldiers. And several thousand more USAF airmen should be added to that number.
Deutsche Welle has this article about current us military locations and personnel number in Germany: https://www.dw.com/en/us-military-in-germany-what-you-need-to-know/a-49998340
